I have a 2013 G37x coupe and my wires got cut leading to my radiator after a accident, car got restored by body man but he didn't want to mess with that part of the job the problem is my car is overheating but its not leaking no antifreeze or anything so i think it has to do with the wires that got cut here are some pics its were the windshield washer tank is

 

They look like ground wires, but you could get a volt tester to make sure.

 

Check your fuses too, might be the one that controls the fan.

 

I go to school so when I get home I will check the fuses and update y'all thanks

 

I went to a local electric mechanic today and he put on the computer and said these codes came back b1153, b1081, b1134 and said that am missing some wires and it needs to be traced also said that the fan may be the problem for overheating these codes that I have are pertaining to the curtain module, side module, pre tension, just wanted to know if I had my srs module reset already would these modules have to be changed too because I thought that the one under the armrest controlled all of them not sure though
